Recruitment in fishes, defined as the survival of a cohort through the first year of life, can be highly variable and affected by small changes in biological and physical factors. Much of the historical focus into the sources of recruitment variability has concentrated on the larval stage, but recent attention has shifted to the relatively longer juvenile period. Spawning behavior that results in the production of multiple cohorts over time and space within a year-class may dampen recruitment variability by decreasing natural mortality risk. The bluefish (Pomatomus saltatrix) is a migratory marine species that produces multiple cohorts of …

The Hudson River estuary (HRE) is a well monitored aquatic resource and much secondary data exist for this system. We developed two objectives based on accessible HRE aquatic data. The first objective was to determine if changes in HRE fish community over the time period (1974 to 2005) years are correlated to local and regional climate. We addressed this objective by employing a multivariate statistical approach. We confirmed that the HRE fish community structure has changed over the time period (1974 to 2005). These changes are correlated with local hydrology (freshwater flow and water temperature) and regional climate (Atlantic Multidecadal …
